This imeution relates to luhricating dei to hihricating devices iecizilly adapted for luhri rating oi elevators and the like.

inc/z :4 re 0S the guide mus .kri object of the invention is to provide lD'lPlOYOLl lubri ting; me w" ich will automatic-(ally sup; elymovuble parts with which it is associated, enough lubriusnt to'insure el tire luhricatioin but will not-supply too much lubricant and will not'ceuse u \i'uste oi the lubricant. I

More partieulerly the invention aims to providelubricatingineuns for elevator guide rails and the like. which ineybe mounted on theelevetor car and curried therewith and operzitedin such manner that it Will lubricate the gl'iide mils proportionately to the travel of the our thereoi er; The invention zzin s further to provide an auto inatic lubrii t? device which will handle lubricant in quid form without weste, eitherthrough excessive application oi" the lubricant to the port tobe lubricated 01' through lenhc -go or spilling; from the lubricz'zting nieuns it elf. llinportent 't'eutures oi the invention are the novel wiping;- ineei applying the lubricant to the rail (mother port to oe lubricated. the novel means for supplying lubricant to the wiping hie-(ins, the means for adjusting the lubricant supplying means to vary the amount of lubricant supplied at a single operation, the construction and d1- rengement o? the lubricant reservoir and wiping means so that lubricant supplied to imp; description and claims \vhcn considered in connection with the accompanying drawings in which Fig. 1 is a perspective view of a lubricating (lei'ice embodying the invention, parts being broken away to show parts otherwise concealed;

Fig. 2 is a bottom plan View of the Wiping means and the holder therefor; and I 1g. (-3 IS a perspective detail showing the constnuztion oil the interior of: the support for the \viping means.

The illustrated lubricating device which is adapted l'o'be curried upon the top of an elevator car,prelereblyabove the guide shoe which embraces the rail, comprises a reservoir Q for the lubricant said reservoir having lugs lby which it may be attached to the cor. Projecting to one side of the resor voir and near its upper end is the support 6 for the wiping means by which the lubricant is applied to the elevator rail 8, shown in dotted lines and also partly broken away. The support 6 is preferably integral with the reservoir 2 and comprises a chamber having a slot or guide in which the rail is received and in which the rail comes into contact with the wiping means confined in said chamber. A common cover 10 adapted to cover both the lubricant reservoir 2 and the support 6 for the wiping means.

Ti lie illustrated Wiping means comprises a pad 12 of :lelt or other suitable absorbent material confined between upper and lower holding members 14; and 16 respectively, this pad being provided with a slot to receive the elevator guide rail and also being out in at 18 to permit the pad to adjust itself readily to the rail. The holding members 1 1 and 16 protect the Wiping means from wear without in any way interfering with its wiping action, and may be of any suitable material such as vulcanized fibre. There are pref- 1 11 ervoir, and conduit means leading into the reservoir to convey thereto any excess lubricant.

14. In a lubricating device, in combination, a lubricant reservoir, wiping means for applying the lubricant to the part to be lubricated, means for supporting said wiping means at a level above the lubricant in to embrace three sides of the rail to be lubricated, a divided holder confining the sides of the wiping face of said absorbent material, a casing supporting said holder, and means yieldingly pressing the holder towards the rail arranged to maintain said absorbent material yieldingly in contact with all three sides thereof, said means comprising springs engagingsaid divided holder and carnmingfaces forming part of said casing.

16. In a lubricating device for elevator rails and the like, in combination, Wiping means comprising absorbent material shaped to embrace three sides of the rail to be lubricated, a divided holder confining the sides of the wiping face of said absorbent material, a casing for said holder springs between the holder and casingso constructed and arranged as to hold said holder in said casing, and to exert pressure on said absorbent material to yieldingly maintain it in contact with all three sides of the rail.
